| ip route 0.0.0.0 0.0.0.0 192.168.2.3 255.255.255.0 | 
| set default route (0 source 0 destination) to the speicified IP address with mask. | 
| do sh ip route | 
| list routing in configuration mode | 
| ip route 0.0.0.0 0.0.0.0 FastEthernet 0/3 192.168.2.3 | 
| set default route with defining the interface. This is the faster solution in practice, if the interface is also defined | 
| ip route 192.168.1.0 FastEthernet 0/2 10.0.0.1 | 
| set a static route for accessing 192.168.1.0 network. Do not forget to set the static routing backwards on the other side. |
